Function[CPXA_PSEPU] Involved in a camphor oxidation system. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe ability to detect, characterize, and manipulate specific biomolecules in complex media is critical for understanding metabolic processes. Particularly important targets are oxygenases (cytochromes P450) involved in drug metabolism and many disease states, including liver and kidney dysfunction, neurological disorders, and cancer. We have found that Ru photosensitizers linked to P450 substrates specifically recognize submicromolar cytochrome P450(cam) in the presence of other heme proteins. In the P450:Ru-substrate conjugates, energy transfer to the heme dramatically accelerates the Ru-luminescence decay. The crystal structure of a P450(cam):Ru-adamantyl complex reveals access to the active center via a channel whose depth (Ru-Fe distance is 21 A) is virtually the same as that extracted from an analysis of the energy-transfer kinetics. Suitably constructed libraries of sensitizer-linked substrates could be employed to probe the steric and electronic properties of buried active sites. Optical detection of cytochrome P450 by sensitizer-linked substrates.,Dmochowski IJ, Crane BR, Wilker JJ, Winkler JR, Gray HB Proc Natl Acad Sci U S A. 1999 Nov 9;96(23):12987-90.
